Desiccant Canisters: Increase the Life of Your Pharmaceutical Packaging Product

Pharmaceutical packaging products require utmost care and protection to maintain their quality and effectiveness. Factors like moisture, humidity, and other environmental conditions can significantly affect the shelf life of pharmaceutical products. To mitigate these risks, desiccant canisters are an effective solution. In this article, we will explore what desiccant canisters are, their benefits, and how they increase the life of pharmaceutical packaging products.

What are Desiccant Canisters?

Desiccant canisters are small containers filled with desiccants, which are moisture-absorbing materials. The desiccants used in these canisters can vary, but the most common ones are silica gel, activated carbon, and molecular sieves. These canisters come in different sizes and are designed to fit into various types of packaging, including bottles, jars, and pouches.

How do Desiccant Canisters work?

Desiccant canisters work by absorbing moisture from the surrounding environment. The desiccant material inside the canister attracts moisture molecules and traps them inside its pores, leaving the air inside the container dry. As a result, the moisture-sensitive pharmaceutical products inside the container are protected from the harmful effects of moisture and humidity.

Benefits of Using Desiccant Canisters

There are several benefits to using desiccant canisters for pharmaceutical packaging products, including:

Prolongs Shelf Life

Moisture is a significant threat to pharmaceutical products, as it can cause them to degrade, lose potency, and become ineffective. Desiccant canisters help to absorb moisture, thereby increasing the shelf life of the products.

Prevents Contamination

Moisture can also promote the growth of bacteria and other microorganisms, which can contaminate pharmaceutical products. By using desiccant canisters, you can prevent the growth of these harmful microorganisms and ensure that your products remain safe and effective.

Cost-effective Solution

Desiccant canisters are a cost-effective solution to protect pharmaceutical products from moisture damage. By using them, you can avoid the costs associated with product recalls, product wastage, and other quality control issues.

Versatile and Easy to Use

Desiccant canisters are versatile and can be used with a wide range of pharmaceutical packaging products. They are also easy to use and require no special equipment or training.

Types of Desiccant Canisters

There are different types of desiccant canisters available, depending on the desiccant material used. Some common types include:

Silica Gel Desiccant Canisters

Silica gel is the most commonly used desiccant material in pharmaceutical packaging. It is a highly effective moisture absorber and can be used in a wide range of packaging products.

Molecular Sieve Canisters:

A molecular sieve is another popular desiccant material that has a higher absorption capacity than silica gel. Molecular sieve canisters are often used for products that are extremely sensitive to moisture, such as chemicals and sensitive electronic components.

Activated Carbon Desiccant Canisters

Activated carbon desiccant canisters are suitable for products that are sensitive to both moisture and odors. They can absorb both moisture and volatile organic compounds (VOCs) and are commonly used in the food and pharmaceutical industries.

Clay Desiccant Canisters

Clay desiccant canisters are made from natural clay and are commonly used for packaging products such as shoes, leather goods, and textiles. They are known for their low cost and eco-friendliness.

Calcium Oxide Canisters

Calcium oxide canisters are also known as quicklime canisters and are commonly used for heavy-duty industrial applications. They have a very high absorption capacity and are often used for dehumidifying large spaces.

When selecting a desiccant canister, it is important to consider factors such as the type of product being packaged, the level of moisture sensitivity, and the storage conditions. Consult with a our expert to determine the best desiccant canister for your specific needs.

How to Choose the Right Desiccant Canisters

Choosing the right desiccant canisters for your pharmaceutical packaging products can be crucial to their effectiveness. Here are some factors to consider when selecting the right desiccant canisters:

Packaging Type

Consider the type of packaging you are using for your pharmaceutical products. Different packaging materials may require different types of desiccant canisters. For example, bottles and jars may require different canister sizes than pouches.

Moisture Sensitivity

Consider the level of moisture sensitivity of your pharmaceutical products. This will determine the type of desiccant material you should use and the amount of desiccant needed.

Storage Conditions

Consider the storage conditions of your pharmaceutical products. If the products will be exposed to high levels of humidity or extreme temperatures, you may need to use a more robust desiccant canister.

How to Use Desiccant Canisters

Using desiccant canisters is relatively easy. Here are the steps to follow:

  • Select the appropriate size and type of desiccant canister for your packaging.
  • Place the canister inside the packaging, preferably near the top.
  • Ensure that the packaging is tightly sealed to prevent moisture from entering.

Factors to Consider While Using Desiccant Canisters

While using desiccant canisters, here are some factors to consider:


Ensure that the desiccant canister you choose has the capacity to absorb the moisture present in your packaging. Overloading the canister can reduce its effectiveness.

Humidity Levels

Consider the humidity levels of the storage environment. If the humidity levels are too high, you may need to use more or larger canisters.

Common Mistakes to Avoid while Using Desiccant Canisters

While using desiccant canisters, here are some common mistakes to avoid:

Incorrect Placement

Ensure that you place the desiccant canister in the right place within the packaging. Placing it too low can reduce its effectiveness, while placing it too high can cause it to come in contact with the product.


Avoid overloading the canister with more moisture than it can handle. This can reduce its effectiveness.

How to Store Desiccant Canisters

Desiccant canisters should be stored in a cool, dry place away from direct sunlight. They should also be kept in their original packaging until they are ready to be used.

The Future of Desiccant Canisters

Desiccant canisters are becoming increasingly popular in the pharmaceutical industry as more companies seek to protect their products from moisture damage. With the growing demand for effective and cost-efficient solutions, desiccant canisters are expected to remain a popular choice for pharmaceutical packaging for the foreseeable future.


Desiccant canisters are an effective solution for protecting pharmaceutical products from moisture damage. By choosing the right desiccant canisters and using them correctly, you can prolong the shelf life of your products, prevent contamination, and save costs in the long run. Using desiccant canisters can be a crucial step in prolonging the shelf life and maintaining the quality of your pharmaceutical packaging products. By considering factors such as packaging type, moisture sensitivity, and storage conditions, you can choose the right desiccant canister for your products. Remember to use the canisters correctly, avoid common mistakes, and store them in a cool, dry place. With the right approach, desiccant canisters can help you save costs and protect your products from moisture damage in the long run.
